.4 Claims.

, 'The object of the present invention is to provide a machine whichwill receive either cans or drums, which will feed said containerscontinu 'ously in a circular path with each container brought intoregistration with one of a plurality of filling nozzles, the lattercommunicating with metering devices of a known type for filling thecontainers with a measured quantity of fluid. As each container isbrought to the beginning of the circular path an appropriate fillingnozzle automatically descends into the container, this being done withrespect to each of a succession of containers, so that a pluralityundergo filling until they reach the end of the circular path. At thispoint the nozzles are retracted from the contain- .erS, in succession,and the containers move away for packing or direct shipment. Acharacteristic of the invention is that the spacing and registration ofthe containers in the circular path is effected by the means which movesthem, such means being pusher arms. There are-two sets' of pusher arm's,each arm of a set-being telesco ic, one set heing for drums orother'la'rge containers and a second and uppermost setbeing -'for cansor other relatively small containers. *Each set of arms lies above itsown support for the'com t'ainers. The supports are trackways in "theterm of elongated rollers, inwardly tapered, the entire upper tra'ckwaybeing-removablein nrd'er thatthe lower trajckway alone mayiunction withrespect todrums or large containers.

The invention will be described with reference to theaccompanyingdrawings, in which:

Rererring to the drawings, I have shown at l a plurality bi vers s-1standards which support 5 angle rons-z which pivo llycarry between thema plurality of tapered rollers 3'. As shown in Fig. 8 these rollers arepreferably formed of tubing and an agile! projects ate'ach end thereofafter passing through i'sks 5. The angle irons -2 are bent to o rrn' ac'ircul r partly around a rotary tuloiilar axial ine her 4. at one endthe assemlily of ca e ne bus 2 for-msfan entrance length and theopposite end forms an exit len'gth, as sh-own'm'ore particularly inFigs.2 and 3.

The tubular standard 4' is, as shown in Fig. 4, provided with a flangdb'as e at ta: closed-by a t1iat)la ifagnfi 5 and" thence mounted uponthe flanged upper end of'atiiloular dependin'g' e'xten sionfi whichenters thelearing' boss-'11: of a gear box '7. fI-h redii'cdlowfendofmember-G of the tubular standard Wcarriies a worm wheel 8 en}- gaged-bya worm 9 (Fi-g'j 4?. This Worm is on a shaftl ll which projectsirom oneeiid or the gear box, the jeiipiose'c'l end thereof carries fa pulley ,ll (Fig. 2) lea g'to'apull'ey"f2 carried by'a' shaft driven by tablereduction gearing "(not shown) i a sea g g 1.3. th dfl e a ne beingdriven through a uuey "l f'rotatedby a pew Ii: l eadihgto the pulleyll-5:1: of the motor it. This motonmay be" a 's ndard'variahle speedmotor, and 'for,convenience n o rolling the speeds'i have provided;speedreducing shaft I! operated .b e a the E 8 'f jiii .P'Q io t rekway.

For inoving drums or other relatively large contain er s ,on the rollersoft-lie lower "trsekway, there s manages the'tubul'a'ir standard a asleeve l9 7 'pr ease pluralityof'tubii- ,larcarr'iersjflgc t ibleconduit 28 at the end of which is a nozzle 29, each nozzle beingsupported by a chain or other flexible holder 30, leading downward froman endwise movable rod 3| mounted in a bracket sleeve 32. Carried by thelower end of each rod 3|, is a roller 33 wh i ch rides upon a camtrack34 supported by standard I. At both the entrance and exit portions ofthe cam-track it has a high section. That is to say, when the containersreach such position that they are initially and successively engaged bythe pusher arms, the respective engaging pusher arms will lieimmediately over the high point of the camtrack and immediately adjacenta nozzle which will be held above the can or other container. However,as the container is moved further the roller of the appropriate rod 3|moves to the lower area of the cam-track and the nozzle is dropped fromthe position of Fig. 6 to the position of Fig. '7 and hence into thefilling opening of the container. The appropriate metering valve will beset to institute the flow of oil or other fluid at this point.

As shown in Figs. 9 and 10 the attachment of the tubular members of thepusher arms to the ring 21 may be by means of straps 35, and adjacentthe straps, each tubular member 20 may be provided with a set screw 36for holding the appropriate rod 22 in either projected or retractedposition. Also, it will be noted from Fig. 1 that the nozzle holdingrods 2| are preferably formed with yoke ends so as to embrace andprovide guiding surfaces for the flexible conduits 2B. When small cansor other containers are to be filled a detachable trackway consisting ofangle irons 2x, rollers 3x and supporting arms In: is employed. Thelower ends of the supporting arms Inc may be forked to receive the bolts38 by which the upper trackway may be detachably held upon the angleirons 2 of the lower trackway, although the inner supporting arms In:may, as shown in Fig. 4, rest directly upon the cam-track 34.

For cooperation with the upper trackway there is provided an upperpusher assembly consisting of the hollow tubular members 20:1: carriedat their inner ends by a sleeve or collar I93: on standard 4 and carriedat their outer ends by a ring 2hr. In the embodiment shown the ring 2L1:is but a spacer member for the pusher arms, but it may be arranged toafford a positive support therefor. Each hollow member 209:telescopically receives a pusher arm 20:.

In the operation of the machine with respect to large containers such asoil drums, the drums are successively moved forward on the rollers 3,Fig. 2, at the entrance end of the trackway as shown by the arrow on theupper portion of Fig. 2. Each container will be met by one of the pusherarms 22 which, as shown in Fig. 3, lies adj acen't one of the nozzles29. In the filling of the large containers the upper trackway with itsrollers 31: will have been removed and the pusher arms 2211 will havebeen retracted. The said large containers will be received within thecircular path of the trackway while the appropriate nozzles are held bythe high point of the cam-track. In a short, continued, movement of eachcontainer a nozzle will be dropped into the filler opening so that thepre-set metering valves may begin the filling operation. The fillingproceeds in the slow movement of the appropriate containers until theyreach the exit end of the trackway whereupon the high point of thecam-track is utilized to raise the nozzles in succession and thecontainers are discharged.

It will be understood that various modifications may be made in the formand arrangement of the. elements constituting the embodiment illustratedin the drawings without departing from the spirit of the invention.

Having described my invenion, what I claim and desire to secure byLetters Patent is as follows:

1. A can and drum-filling machine, consisting of a tubular standard andmeans for rotating the same, a platform embracing and moving with thestandard, a plurality of metering valves carried by the platform, amanifold provided by the standard and communicating with the meteringvalves, said manifold being adapted for communication with a fluidsupply, a flexible conduit leading from each metering valve, eachconduit having a discharge end, means applied to each conduit andcomprising a push rod for raising and lowering the conduit, verticalsleeve members connected to the tubular standard and rotating therewith,the sleeve members receiving said push rods, propelling rods extendinglaterally from the tubular standard and rotating therewith, a trackwayfor cans and drums, said trackway at least partially surrounding thetubular standard and below said propelling rods, and a second trackwayhaving elevated and relatively depressed sec tions with which the pushrods successively engage.

2. A can and drum-filling machine constructed in accordance with claim 1in which the tubular standard is closed at its base section and isformed with upper lateral feed ducts leading to the metering valves, theinterior of the standard having the function of a reservoir and, withsaid ducts, acting as a manifold.

3. A can and drum-filling machine constructed in accordance with claim1, in combination with a plurality of axially directed sleeves projectedfrom the standard and receiving said propelling rods.

4. A can and drum-filling machine constructed in accordance with claim1, in combination with a trackway supporting frame, upper and lower setsof axially directed sleeves projecting from the standard, such sleevereceiving one of said propelling rods, and means on said trackwaysupporting frame for mounting a second trackway intermediate the twosets of said sleeves.
